The Dutch Banking Association (NVB) for a couple of years now makes internetbanking fraud numbers in NL public, with updates every half year. The damage for the first half of 2012 was €27.3M, compared to €35M for the whole of 2011 (see graph below, with the amount for 2012 calculated by simply doubling the first half of 2012) . The relative increase, again calculated by simply doubling the 27.3M to get a number to compare to the €35M, is roughly 1.5 times. This means the growth is less than it was the previous years (see the graph below). Also if you compare the first half of 2012 to the second half of 2012, the growth has decreased to 14%. This does not mean that I’m optimistic, the fraud still increases, and the absolute numbers are also becoming worrisome. With ~11M internet banking users, this is ~€5 per user, which is IMHO significant.
As one would expect, the NVB mentions that attacks are becoming more malware and less ‘old-fashioned phishing’ based. I’d be very interested to see statistics on internet banking fraud with the increasing popular mobile banking apps, but the NVB unfortunately does not provide these numbers.
